How did turbo tax file my refund

Only you can initiate the filing of a tax return, either by e-filing or printing the tax return for mailing.

Did you do this?

You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large Orange button labeled "Transmit my returns now".

After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.

It said I can't e-file i don't know why 

If I used the mail feature dose turbo tax mail my refund to the irs
